DUST-DISTRIBUTING CAR.

Application led'December 29, 1924. Serial No. 758,750. .i

To all whom t www concern.:

Be it known that I, ROBERT. D. BEA'rrY, a citizen of the United States,residing at Birmingham, in the county o-f Jederson and State of Alabama,have invented a new and useful Dust-Distributing Car, of which thefolllowing is a specification.

This invention aims to\ provide a novel /form of distributing car whichmay be used for rock dusting coal mines, the invention comprising novelmeans for feeding the dust from the car, and for distributing the dustin the mine. I

It is ywithin the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

`With the above and other objects in View which will appear as thedescription proceeds', the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings Figure4 1 shows in top plan, a deviceconstructed in accordance with the invention; Figure 2 is a sideelevation ;l Figure 3 is a longitudinal section on the line 3--3 ofFigure l; Figure 4 is an end elevation; Figure 5l is a transversesection; Figure 6 is a section ltaken on the line 6-6 of Figure 1;Figure 7 is a section taken on the line 7-7 of Figure 1.

The car comprises a body 1 which may be made in variousways, withoutjeopardizing the utility of the invention. As shown, but not ofnecessity, the body comprises ends 2 and 3, sides 4 and downwardly andinwardly slanting vbottom members 5. End cross pieces 6 and intermediatecross pieces 7 are connected to the bottom members 5.

The frame 8 lof the car, like the body 1, maybe made in many wayswithinthe scope of the invention. In order to present a concrete embodiment,the frame 8 is delineated as including side bars 9 and end ing similarlyconnected to the intermediate cross pieces 7 of the body 1. Axles 15`are supported ai; 16 onthe side bars 9 of the frame 8, and carry wheels17 adapted to move along a track 18. v

At the longitudinal center of the body 1 and at the lowermost portion ofthe body is located a trough-like member 19 which extends longitudinallyof the car, the member 19 having lateral flanges 2O which are connectedto the body forming members 5. At one end, the trough-shaped member 19is closed, as shown at 21, in Figure 3 by a portion ofthe lend 3 of thebody 1, the opposite end of the member 19 communicating with a vertical,chute 22, as shown at 23, the chute being mounted on the end 2 of thebody 1. As shown `at 63, the chute'22 communicates with a conduit 24which extends through the lower portion of thechute, the conduit beingdisposed longitudinally vof the car. Above the conduit 24, the chute 22carries a removable screen 25.

i The conduit 24 has an upwardly extended end 26' communicating with asuction and blower mechanism'27 mounted on a platform 28 carried by theside bars 9 of the car frame 8.- YThe shaft `29 of the suction andblower mechanism 27 is coupled, as shown at 30, to the shaft 431 of amotor 32 mounted on the platform 28. The motor 32 may be of any desiredsort, but it is suggested that an electrical motor be used if considereddesirable. The shaft 29 of the suction and `blower mechanism 27 carriesa beveled pinion 33 meshing with a beveled gear 34 on av shaft 35extended longitudinally of the car,

the shaft being j'ournaled in a bearing 36 on the platform 28. At itsinner end, the shaft 35 is supplied with a beveled pinion 37 mesh#ingwith a beveled pinion 38 on a shaft 39 disposed transversely of the.car, the shaft 39 being journaled in a casing 40 supported by a hanger41 on the end 3 of the car body 1.

Within the i casing 40, the shaft 39v is equipped with a worm 42,meshing wi a worm wheel 43 on'a shaft 44 extended longitudinally of themember 19 and journaled in the casing 40, in the part-21 of the end wall3 of the car body, and inl the chute 105 angle member, extended betweenthe ends' 2and 3 andsupported upon and connected an inverted anglemember, is mountedy for" reciprocation onthe grate 46, ythe slide 47.and the grate 46 bein equipped with openinv` s 48 which are a apted, tobe` brought in o registration when the slide is' moved .endwise'u Theslide 47 carries laterally extended rakes 49, which move in close prox.

imity to the bottom members 5. At one end, the slide 47 has an arm 50,mounted toreciprocate in the .end 2 of the car body 1, the arm 50 beingconnected-in any suitable way, as shown-at 51, to the lower end of anoperating member 52, preferably a lever,

the lever being fulcrumed intermediate its ends, as shown at 53, on theend 2 of the 'car body 1. c

In practical operation, the finely divided material with which the mineis to be dusted, is placed in the car body,v 1. Through 'the medium ofthe lever 52, the slide 47 may be moved endwise, so as to bring theopenings 48 to the slide and of the grate 46 more or less intoregistration, thereby to regulate the amuont of material which passesdownwardly into the trough-shaped member 19, and to cut off the supplyof material to the trough-like member 19, upon occasion. The material,passing through the openings 48 of the slide 47 and the grate 46, isengaged bythe screw converyor and is advanced to the right in Figure 3,the material passing into thevertieal .chute 22, the screen 25exercising its obvious oiiice. From the chute 22, the material passesthrough the o enin 63 into the conduit 24,

-and when ab ast o air passes through the conduit, the-dust or materialis driven out 1nto the mine and distributed through a suitable nozzle(not shown).

The blast of air throughthe conduit 24 is createfd, of course, by thesuction and blower mechanism 27, the shaft 29 of the suction and blowermechanism being driven -rom the shaft 3l of the meter 32. The

driving train for the shaft 44 which carries the conveyor 45 includesthe beveled pinion 33,' the beveled pinion 34, the shaft 35, the beveledygear 37, the beveled. gear 38, the shaft 39, the worm 42, .and the Wormwheel 43. Y

Having thus described the invention,

what is claimed is ,1. In a device of the Rclass described, a

lwheel-mounted frame, a body carried by the frame,a blast conduitsupported by the frame, means for producing ablast in the conduit, aconveyor in the body and discharging into the conduit, means foroperating the` conveyor, and mechanism for regulating .the flow ofmaterial from the body to the conveyor, said mechanism being movablyunder the control of an operator and practically equal in length to theconveyor thereby to securean even supply of material to the conveyor, aperforated slide mounted to reciprocate on the grating and governing thelow of material from-the body to the conveyor thereby to avoid aclogging of the conveyor, a longitudinal blast conduit into which thetrough-shaped member discharges at one end, meansfor supplying a blastto the conduit, means under the control of an operator for moving theIslide, and means for operating the conveyor.

In testimony that I claim the foregoing as my own, ture.

ROBERT AD. BEATTY.
